概述

BusAdapter BA 2xRJ45

BusAdapter BA 2xFC

SIMATIC ET 200SP 的接口模块具有一个用于总线适配器的通用 PROFINET 接口。 使用适宜的总线适配器，可根据特定应用的要求来调整连接类型：

• 对于具有中等机械负荷和 EMC 负荷的标准应用，可使用 BA 2xRJ45 总线适配器。该适配器具有用于标准 RJ45 插头的两个插座。
• 对于各个部件要承受较高机械和/或 EMC 负荷的机器与系统，建议使用 BA 2xFC 总线适配器。 在此情况下，将通过 FastConnect 端子来直接连接总线电缆（与 PROFIBUS 连接器类似），这已在无数应用中得到证明。采用这种技术时，组装极为迅速，与 RJ45 插入式连接器相比，抗振性和抗电磁干扰性均提高 4 倍。
• 带有光纤电缆连接用总线适配器可用于覆盖两个站和/或较高 EMC 负载之间的较高电位差。

该总线适配器的另一个优点是： 其目的是：修理出现问题的 RJ45 插座、后期转用可靠的 FastConnect 技术或者光纤连接技术时，仅仅只需更换该适配器。

以下接口模块通过总线适配器来提供 PROFINET 连接：

• IM 155-6PN 标准型
• IM 155-6PN 高性能型

应用

ET 200SP BusAdapter “BA-Send"

BA-Send BusAdapters are used whenever an existing ET 200SP station is to be expanded with IP67 modules of the SIMATIC ET 200AL.

The SIMATIC ET 200AL is a distributed I/O device with degree of protection IP65/67 that is easy to operate and install. Due to its high degree of protection and ruggedness as well as its small dimensions and low weight, the ET 200AL is especially suitable for use at the machine and on moving plant sections. SIMATIC ET 200AL enables the user to access digital and analog signals and IO-Link data at low cost.

SIMATIC BusAdapters

In standard applications with moderate mechanical and EMC loads, SIMATIC BusAdapters with an RJ45 interface can be used, e.g. the BusAdapter BA 2xRJ45.

For machines and systems in which higher mechanical and/or EMC loads act on the devices, a SIMATIC BusAdapter with connection via FastConnect (FC) or fiber-optic cable (SCRJ or LC) is recommended. Likewise, all SIMATIC BusAdapters with a fiber-optic cable connection (SCRJ, LC) can be used with the increased loads.

BusAdapters with connections for fiber-optic cables can be used to cover high potential differences between two stations and/or high EMC loads.

An overview of the essential properties of the PN interfaces is shown in the table below
